Not sure if this is relevent, but I received the same error on VS2015 CTP
6.  I changed the code to std::integer_sequence< std::size_t, I ... > to
get around it.

On a related note, on CTP6, Microsoft has changed the include paths for the
CRT.  For some reason some boost build generated files with names like
'b2_msvc_14.0_vcvarsall_amd64.cmd' were not regenerating after I upgraded
to CTP6 which resulted in a stale INCLUDE environment variable an
consequently, a failed build.  Manually deleting the files corrected the
problem.
